What causes the modern washing machine to smell inside the drum?

There could be several reasons why your washing machine smells inside the drum.

Here are a few common causes:

  1. Dampness and mold: If you leave wet clothes or damp laundry in the machine for an extended period, it can lead to a musty smell. This dampness can promote the growth of mold and mildew, causing an unpleasant odor.

  2. Residue buildup: over time, detergent, fabric softener, and other laundry products can accumulate inside the drum, forming a residue. This residue can harbor bacteria and contribute to unpleasant smells.

  3. Clogged or dirty filters: the filters in your washing machine, such as the lint filter or drain filter, can become clogged with lint, debris, or detergent residue. This can restrict water flow and create a breeding ground for odor-causing bacteria.

  4. Improper ventilation: If your washing machine is not properly ventilated, it can trap moisture inside, promoting mold growth and resulting in odours.

Here are some steps you can take to address the smell:

  1. Clean the drum: Run a wash cycle with hot water and no clothes, adding white vinegar or baking soda to the detergent dispenser. Vinegar and baking soda can help remove odors and eliminate residue. Alternatively, you can use a specialized washing machine cleaner.

  2. Clean the detergent dispenser and filters: Remove and clean the detergent dispenser, as well as any removable filters. Use warm, soapy water to clean these parts and remove any buildup.

  3. Leave the door open: After each wash, leave the washing machine door open for some time to allow air circulation and prevent moisture buildup.

  4. Check the drainage: Ensure that your washing machine's drainage system is functioning properly. Clean out the drain pump filter regularly to prevent clogs.

  5. Use less detergent: Excessive use of detergent can leave behind residue. Follow the manufacturer's instructions for the appropriate amount of detergent to use.

  6. Regular maintenance: Perform regular maintenance on your washing machine, including wiping down the drum and seals, and cleaning the rubber gasket if your machine has one.

By following these steps you should be able to reduce or eliminate the odor in your washing machine. If the problem persists or if you suspect a mechanical issue, it may be best to contact a professional appliance repair technician for further assistance.
